PURPOSE
The vast majority of ruptured aneurysms of the anterior communicating artery typically present with subarachnoid haemorrhage. Isolated visual complaints are very uncommon in this setting. We present an unusual case of a patient with an acute retrobulbar optic neuropathy, secondary to a ruptured anterior communicating artery aneurysm.
DESIGN
Observational case report.
METHODS
A 29-year-old woman was assessed for an acute, isolated unilateral optic neuropathy of unknown origin. Although an initial encephalic MRI was believed to be normal, an underlying ruptured anterior communicating artery aneurysm was eventually diagnosed when the patient became stuporous because of intracranial bleeding.
CONCLUSIONS
Occurrence of an acute retrobulbar optic neuropathy may be the initial isolated sign related to a ruptured anterior communicating artery aneurysm, prompting an appropriate neuroradiological assessment.
目的
绝大多数前交通动脉瘤破裂通常表现为蛛网膜下腔出血。在这种情况下，孤立的视觉症状非常罕见。我们报告一例不寻常病例，患者因前交通动脉瘤破裂继发急性球后视神经病变。
设计
观察性病例报告。
方法
一名29岁女性因不明原因的急性、孤立性单侧视神经病变接受评估。尽管最初的脑部MRI被认为正常，但当患者因颅内出血陷入昏迷时，最终诊断出潜在的前交通动脉瘤破裂。
结论
急性球后视神经病变的发生可能是前交通动脉瘤破裂相关的最初孤立体征，促使进行适当的神经放射学评估。
